o create a separate tag for each object allocated with bus_dmamem_alloc so
the tag's maxsize is setup appropriately; this reduces memory allocation
for the queue descriptors from 16M to what it should be and also fixes
memory allocation for public key operands
o release bus dma resources on detach so module usage doesn't leak
o remove public key op disable now that bus dma memory allocation is fixed
o collect attach error handling in one place

_nexus_dmamap_load_buffer()
- implement nexus_dmamap_load() in terms of _nexus_dmamap_load_buffer().
Note that this is untested, as this code is not currently used (but
might be later for UPA devices).
- move BUS_DMAMAP_NSEGS to bus_private.h
- disable the ecache flushing in nexus_dmamap_sync(); it should not be
needed, although the docs are not entirely clear on that.
some trick is necessary to prevent further BSD geoms from attaching to
that. Our old trick was to make sure we don't attach to a geom from
the "BSD" class, but this doesn't work if an intermediary geom obscures
this fact. Instead, calculate the MD5 checksum of the label we target
and ask if anybody below us loves that label. If they do we don't.

- move some constants into iommureg.h
- correct some comments
- use KASSERT() in one place instead of rolling our own
- take a sanity check out of #ifdef DIAGNOSTIC
- fix a syntax error in normally #ifdef'ed out debug code
- tweak the announce message a bit
- remove '\n's from a few panic() calls
- don't use the DVMA base adress the firmware reports; instead, figure
it out from the appropriate register on Sabres and let the IOMMU code
choose it on Psychos. This also makes the IOMMU TSB size freely
selectable.
2.) pass the requesting child device (instead of the bus one) up when
handling interrupt resources
3.) remeber to mark the resource list entry as unused in
sbus_release_resource().

The leak in lseek was introduced in vfs_syscalls.c revision 1.218.
The leak in do_dup was introduced in kern_descrip.c revision 1.158.

Otherwise, the scsi devices that it is trying to issue commands to may
have gone away. This is what caused shutdown to hang on ia64 systems
with mpt scsi controllers. The bus system has torn down the device tree
and reset the mpt controller etc, and suddenly along comes dashutdown
and wants to issue a few more scsi commands.... <HANG!>
This shouldn't work on i386 either, but it seems to work solely due
to luck.
o Expand variables correctly.
o Set variables for each event.
o rewrite event loop to execute the commands in the config file, rather
than the hard wired generic command
o better(?) debug when running -d
o sort vectors of actions so that we just have to search for the first
one to match rather than the best one that matches.
o better attempts to clear all resources used on 'restart'
o Remove now bogus comments
MFC After: 1 centiyear
Add support for GCC's --test-coverage --profile-arcs options.
Add code to call the functions listed in the .ctors section, these are
used to string the per .o file counter blocks into a linked list.
Add empty __bb_fork_func() to cope with GCC magic gandling of exec*()
named functions.
To add support for other platforms should be trivial, but involves
determining the exact data-types gcc uses on that platform.
Minimum Acceptable Value: _POSIX_LOGIN_NAME_MAX.
The comments at the bottom of this file claim sysconf(3) provides this value,
but it seems sysconf(3) hasn't implemented this yet.
